Trend Micro's promise with this product is that users will "never click an update button again," and Titanium honors that promise. In fact, there is no update button at all. Everything is done behind the scenes. For set-and-forget security, it doesn't get much simpler than that.
If you're a more advanced user, you may want to look elsewhere for a suite that offers more fine-tuned controls. But if you're looking for something that provides good protection and doesn't require you to fiddle with settings, Trend Micro Titanium Internet Security is worth a look.
